Weekend game.
I'm also unfamiliar with livechat, but want to become familiar with it if you want to learn together (though discord seems rather simple).
Otherwise, I'd be fine running a one-on-one with you on sunday nights, particularly if you can post two or three times sunday night (I'm night shift here in central timezone, so multiple posts would need to be over night), though a single post on saturdays can be done if you want just two posts per weekend.
